Abstract: A method of driving a display panel includes compensating first pixel data corresponding to a first pixel of a plurality of pixels in the display panel based on at least one of a first decision, a second decision, or a third decision and generating a first data voltage corresponding to the compensated first pixel data. The first data voltage is applied to the first pixel through a data line. The first decision includes determining, based on a position of the first pixel, whether compensation for the first pixel data is required. The second decision includes determining, based on previous subpixel data and present subpixel data for the first pixel, whether the compensation for the first pixel data is required. The third decision includes determining whether the first pixel data complies with a compensation avoidance condition.
